How does it work the session from Assistant API pricing

[jorgeguerrabrazil]

I am still face issue with assistant api pricing.
What does it mean a session?

@landongarrison

Code Interpreter is priced at $0.03 / session. If your assistant calls Code Interpreter simultaneously in two different threads , this would create two Code Interpreter sessions (2 * $0.03). Each session is active by default for one hour, which means that you would only pay this fee once if your user keeps giving instructions to Code Interpreter in the same thread for up to one hour.

Still, it makes no sense.

Example below. One day I was charged several times, other day just one. Even though, in both case, I have used the assistant more than one time.
The point, I have created an assistant, and want to change the issue, at least, the cost from openAI, but, I have not idea how to charge fairly for the assistant session. It does not seem clear to me the rule used.

[Solved] Assistants Code Intepreter API - How is session pricing defined?

Hi OpenAI team, First off, congrats on an amazing Dev day, you guys really do deliver and it’s refreshing to get a tech event to be excited for again. Amazing work! I’m trying to understand the pricing as it’s listed as $0.03 per session to use the code interpreter tool. My question is about how a session is defined. Is a session defined as: a. I send a query that uses code interpreter and that is $0.03 for one code interpreter usage (i.e. code interpreter executes code = $0.03)? So if a chat…
